R001? CONSTRUCTION.

Specification of Letters Patent.

Patented Sept. 16, 1913.

Application led August 5, 1910. Serial No. 575,675.

To all Aw/wm it 'may concern Be it known that l, Huxnv I". lViNiiuL- MANN, a citizen oil. the United States, residing at Nebraska City, in the county o't` Otoe and State of l'ebraska, have invented new and useful Improvements in Root' Construction of which the following is a specification.

The invention relates to roofing,r and more particularly to the class o't root constructions or coverings.

The primary/object of the invention is the provision of a roofing or covering in which the material thereofl is rendered iinpervious to water, thus preventing leakage of the same, and at the same time excluding heat and cold or moisture from a building'` A nother object of the invention is the provision of a rooting or coveringr which will bc light in weight, yet possessing the requisite strength and durability, and also that. will resist fire, hail, water, moisture, heat. cold, sounds, and lightning, thus increasing the lite of the roofing.

A further object ot' the invention is the provision of a rooting or covering construetion which possesses innumerable advan tages and superiority in rooting, heretofore well known in the art, and being simple in construction, and one that is inexpensive in the production thereof.

The invention resides generally in the formation oli-a composite rooting or covering' combined with rein tort-ingr means, thus giving' rigidity and strength thereto, and at the name time compensating t'or expansion and contraction thereof by raison ot' climatic changes.

lVith these and other objects in view, the invention consists in the conatruction, combination and arrangement olf parts, as will be hereinafter more full;r ilescribed, illus lrated in the accompanvingl drawings and pointed out in the claim hereunto appended.

ln the drai Mfrs: Figure 'l is a lrae'mcir tary top plan view ol' a rootingr constructed in accordance with the invention. Fie'. 9 is a similar View, the annie being partly,V brohcn away. Fig. 3 is :i transicrse :,ectinnal vicw on the line a--V ol Fig. l. Vie. -fl is a trae'- Inentary perspective view oll thc metallic:

lath used in the rooling construction. llie'.

5 is a detail perspective view ot' one ol.' the tie or bonding'rods.

Similar reference characters indicate correspondiingr parts throughout the several views oi the drawingr.

tetex-ring to the drawings by numerals, 5 designates the vertical walls of a building which is provided' with sheeting 6 of any suitable material, and upon which the composite rooting' is placed, as will be hereinafter more fully described. superimposed upon the upper face of the sheeting 6 are a plurality ol" plies ot felt 7, the same beingr suitably impregnated with tar-pitch, and these plies entirely cover the said sheeting so that their edges will contact with the inner laces ot' the vertical walls 5 rising a slight distance above the sheeting at the top of the buihling. 'lhe outermost ply of :telt 7 is coated with any suitable waterproof paint'. ExtendingV across the outermost ply of felt T at intervals thrcughout the area of the top ot the building' are tie or bondingr rods 8, the ends ot' the same being' passed through the vertical wall 5 and to which are suitably secured disks or anchoring plates Sl, the lattcr contacting with the outer l'aces of opposite walls ot the said building.

lloslinfhr upon the tie or bonding rods S and spaced trom the outermost ply 7, is a metallic luth` the saine being: constructed trom a siinrle piece ot sheet metal cut to providc spaced parallel webs lil united to cach other bv means ot` ,liagonallv disposed connecting strips ll. the webs` l0 beiner inclined relative lo the uppciply of l'elt 7, thereby cll'cctingr a wa\cd formation lo the said latli throughout thc entire area thereof. 'llic .onnectin} stripsl ll uniting the webs lll are spaced at intervals l'roin cach other. so as to provide suitable `laps between the Said strips ll l'or a purpose` as will be hereinaller more l'ullv dimcribcd. Upon thisl metallic, lalh is arranged a ccmcnlitious block lz?, tbe saine being prel'crnblv composed ofi two parts ol' sand and onc part ot' cement, thorou l 'bl\v connninirlcd or mixed. the composition bcinu' applied to the metallic lath when in a sol't state. so that the substance will pcrcolate through tbe spaces between the strips ll and wcbs l() of tbc lalh` wherebv thc latter will niatcriall)v rcint'orce the substance wllcn liardcncd. ll will bc ob` vious that bv rcrxson ol tbc disposil iol ol' tbc inclincd wcbs lll and also the strips ll, this substance when in`a sott condition will be prevented from spreading or running; While being poured or (.itvherwise distributed over the metallic lath.

In the upper taee of the block l2 are formed spaced longitudinally and vertically disposed channels or grooves 13, the vertically disposed Lgrooves interseeting said lon.- gitudinal groves and into which is poured pitch or asphaltum 14, when in a molten condition, the pitch or asphaltum entirelyl lilling the channels or grooves which extend only through substantially onedialf of the thickness 01"' the block l2D By reason of this construction, the block l2 is prevented from breaking caused by expansion and contraetien due te exposure to climatic changes or variable Weather conditions.v

The metallic lath interposed between the tie rods 8 and the cementitious block by reason of its inclined webs l0 relative to the plies of telt serves to bond and set the substance of thesaid block, so as to prevent the runningr of the cement when applied, and also this cementitious substance will be caused, by slight pressure thereon, to enter v the space of interstices between the Webs and the connecting;r strips 11, thus assisting in the proper-setting of the cement constituting the block. Engaging the webs l0 of the said metallie ath and the tie or bonding rods 8 are staples 15, the same beingl driven into the plies of felt and the sheetingof the roof, thus securely fastening the said lath against any displacement. lt will be noted that by reason of this metallic lath being superirnposed upon the tie reds, it will be elevated from the uppern'iost ply or felt so to be embedded Within the' cen'ientitious block, thereby materially reinforcing the same. @n the upper or outer tace of the cementitious block is applied a cement slushing which ills all peres of the said block, throughout the entire surface thereof', thus rendering the same impervious to Water.

' From the foregoing, it thought that the construction of the invention Will be clean, and therefore a more extended explanation has been emitted. v

llhat is claimed is:

ln combination, oppositely arranged Walls, a layer of pliable material extending longitudinally between said walls, a plurality of spaced-apart tie reds extending' across and above said pliable layer and engaging said Walls, a Woven metal net-Work member extending across and resting upon said tie reds, a plastic layei: suriiiounting said Woven metal member throughout its area and completely embedding the same and said tie rods, and bearing upon said pliable layer, and staples engaging said Wovenmetal members, straddling said tie-rods and driven into said pliable layer oit' material.

ln testimony where-ol I aliix my signature in presence of two Witnesses.
